摘 要
本研究以「徑向振動理論」的數學模式為基礎，以流管模擬實驗了解心臟位置與主動脈弓對血壓波的影響；以及舒張壓與管壁特性的關係。
本實驗以電磁鐵台座輸出脈衝波模擬心臟輸出，以乳膠管(Latex)及矽膠管(Tygon)模擬主動脈；將其轉彎模擬主動脈弓；並拉長管子模擬在生理上的軸向伸長；使用水槽提供系統靜壓模擬動脈系統中的靜壓(舒張壓)。輸入脈衝波後，由壓力轉換器在不同位置量測壓力隨時間的變化，分析後與理論作比較；另外改變靜壓測量管子特性的變化。
本研究證實了管子各個天然頻的振動強度與脈衝位置有關；由模擬主動脈弓的實驗發現主動脈弓的幾何結構及軸向的伸長，可以讓動脈系統獲得較大的徑向振動能量；此外也發現舒張壓變大管壁彈性係數Ep會變小。
